The other bit of big news coming from the Korean peninsula, one not involving nuclear-tipped missiles, is the release of the follow-up single to “Gangnam Style” by PSY—listen to the song, “Gentleman,” here. The song will be performed live for the very first time this weekend at Seoul’s World Cup stadium—the show will also stream on YouTube. But “Gentleman,” for all its global-hit potential, is just another track to spring forth from one the world’s most dynamic musical genres: K-Pop.

This track doesn’t exactly sound like the K-pop you may hear today—it’s definitely from 1992—but it’s thought by many to be the beginning of K-pop. In this clip from a TV competition, you can see the band get low scores while changing Korean pop music.

In 2009, this track—here in its English version—became the first modern K-pop song to break into the Billboard Hot 100.

3. Super Junior-T, “Rokkugo”

One of the more unusual characteristics of K-pop is the proliferation of spin-off groups, and super-siezed boy band Super Junior is no exception. Their group-within-a-group Super Junior-T is worth listening to because their focus is on adapting the Korean pop genre known as “trot,” an older form of Korean pop music that took shape in the early 20th century that some see as the precursor to K-pop.
